Authentic vintage hardcopies were primarily cast in brown (carbalon) and green
(dynacast) urethane, although a few other colors, like black,
show up on occasion. The Rancor Keeper unpainted hardcopy torso is cast in blue urethane, which was not used during the
vintage Star Wars era, however is extremely commonplace on modern day hardcopies. So, how is it that a vintage hardcopy was
crafted in a material which doesn't correspond to its era? During the early 90's, authentic vintage action figure and Micro Collectionsilicone molds were used inside Kenner to create hardcopies for sale on the
secondary market. Thankfully information came to light years back to debunk the claim that these "Blue Harvest" pieces were authentic
prototypes. While they were cast from the original silicone molds, they played no part in the production process. This characteristic
makes them reproductions, although somewhat more collectible than a typical reproduction item due to their place in hobby history.
It's imperative to note that "Blue Harvest" hardcopies hold a small fraction of value compared to authentic unpainted hardcopies.
